Your mains remind me of the ones I used to have some years ago...
Nice.
My grand father gave them to me just before he past away 12 years ago. Rare to see a 3" voice coil on a 12" full range woofer.
I found some interesting things about this very RARE speaker!
Model : JBL L88 Nova
The origin of the L88 Nova requires some historical background. When the project assignment was given to the Wolf office, the simple two-way system immediately suggested that the external design might be made to more clearly express the internal functional elements. The idea of a round grille echoing the form of the low-frequency transducer had seldom been tried before, and when it was, public acceptance did not follow. Two notable examples of this Bauhaus-based approach were an equipment cabinet for Herman Miller (manufactured from 1949 to 1954) by George Nelson and, in 1956, a stunning bass-reflex enclosure for Stephens Tru-Sonic designed by Charles Eames.
